Fix: gcc-9.1 stack frame size warning

gcc-9.1.0 warns about lttng_session_ioctl taking a too large frame size.

lttng-modules/lttng-abi.c:622:1: warning: the frame size of 2240 bytes
is larger than 2048 bytes [-Wframe-larger-than=]

Combine the variables used in the various case of the switch so they are
not duplicated on the stack by the compiler.

Make bitfield.h C++-friendly

This patch changes bitfield.h to be usable in C++11.

It will probably never be compiled as C++ in the context of
lttng-modules, but this is just to keep things sync'ed across projects.

Introduce LTTNG_KERNEL_SESSION_SET_CREATION_TIME

Add trace_creation_datetime to the metadata env field

This allows a viewer to get more information regarding the creation time
of a trace. This information is normally inferred from the trace
hierarchy.

The ABI expects an ISO8601 compliant string value. We leave the
formatting to the trace controller.
